Customer Success Manager

Healthcare is in crisis and the people behind the results deserve better. With more and more data coming from wearables, lab tests, and patient–doctor interactions, we’re entering an era where data is abundant.

Junction is building the infrastructure layer for diagnostic healthcare, making patient data accessible, actionable, and automated across labs and devices. Our mission is simple but ambitious: use health data to unlock unprecedented insight into human health and disease.

If you're passionate about how technology can supercharge healthcare, you’ll fit right in.

Backed by Creandum, Point Nine, 20VC, YC, and leading angels, we’re working to solve one of the biggest challenges of our time: making healthcare personalized, proactive, and affordable. We’re already connecting millions and scaling fast.

Our customer base spans digital health platforms, wearable companies, and health systems – and we’re growing fast in all three. Our CS team is great, but we’re stretched - so we’re on the path to make shifts. The reactive work gets done — onboarding questions, troubleshooting, support coordination. The proactive work is where we’re falling behind: running useful QBRs, spotting expansion opportunities, and catching churn risks early.

This hire is about adding someone with real horsepower. You’ll own a focused book of business – primarily in our digital health segment – from onboarding all the way through renewal and expansion. You’re comfortable in commercial conversations: talking about pricing, pushing on upsell opportunities, and making the case for value when a customer is on the fence. You adapt your approach depending on who you’re talking to – a technical founder needs a completely different conversation than a head of ops, and you can tell the difference quickly.

You’ll also need to genuinely enjoy learning how things work. Junction’s product is technical – APIs, data integrations, health data workflows – and the best person for this role is curious about that, not intimidated by it. You’ll work closely with our CS Leader and feed directly into product and engineering with what you’re hearing from customers.

• →

  Own a portfolio of 25–40 accounts across our digital health and mid-market segment

• →

  Run onboarding for new customers and get them to their first meaningful milestone as quickly as possible

• →

  Conduct quarterly business reviews that are actually useful – not just status updates, but conversations that move things forward

• →

  Proactively identify upsell and cross-sell opportunities and work with our sales team to close them

• →

  Build a real pulse on account health – usage data, engagement signals, renewal risk – and get ahead of problems before they become urgent

• →

  Be the voice of your customers internally. Bring patterns, feedback, and frustrations to product and engineering in a way they can act on

• →

  Help define what great CS looks like for wearable and digital health customers – this is still evolving and you’ll have a real hand in shaping it

• →

  Bring a point of view on how AI tools can make CS work faster and smarter - we have budget and appetite to build this into how the team operates

The metrics that matter most for this role:

• Renewal rate across your book of business

• Expansion revenue from upsells and cross-sells

• Time-to-value (TTV) for new customers – how quickly they hit their first milestone

• Customer satisfaction (NPS/CSAT) across your accounts

• You want a fully defined playbook from day one – we’re still building ours and you’ll have a hand in writing it

• You prefer reactive CS – most of the value in this role comes from going out and making things happen, not responding to inbound

• You’re not comfortable owning commercial conversations – renewals, upsells, and pricing discussions are part of the job, not something to escalate away

• You want to specialize – you’ll touch onboarding, retention, expansion, and internal feedback loops, often in the same week

• Technical products make you uncomfortable – Junction’s API-first platform requires genuine curiosity about how things work, not just a surface-level understanding

• Salary: $110,000 – $140,000 + equity

• Your salary is dependent on your location and experience level

• Generous early stage options (extended exercise post 2 years employment)
